For decades, the world has tried to negotiate its way out of a climate catastrophe – through summits, accords, frameworks and pledges. Yet emissions rise, deadlines pass and the gap between ambition and action keeps widening. The reason isn’t just political failure. It’s a war of ideas. Â
At the centre of that war is Carl Schmitt, the Nazi jurist whose ‘once-taboo’ vision of a world defined by friends and enemies, strong powers and submissive ones, has quietly become the operating logic of our moment. You can see it in Trump’s America, Xi’s China, and the surging authoritarian movements reshaping democracies from Europe to Australia.  Â
Hamilton traces how Schmitt’s shadow has fallen across global climate negotiations – and asks whether a world in the grip of nationalist rivalry can summon the collective will to survive?
